 If you liked Pupa |  ...then you might like Tokyo Ghoul √A |
Both of these anime have similar themes, such as survival, turning into a monster or canibalism. Another simmilarity is the bizarre and almost random structure of the plot, which is because of lack of loyalty to the source material. Also both anime are very bloody, but most of the graphic gore is censored, for better or for worse.
